Project Overview
The Terrain Generation project aims for procedural terrain generation from a density function based on perlin noise, and an implementaiton of the marching cubes algorithm. The project was started early Feb. 2011, and, like my other personal project, is still in development.

An early version of the terrain generator is available on the dowload page above.
The terrain is now fully textured, and looking far more presentable. The viewing distance remains at 1.5km and looks quite nice. But don't take my word for it:
There is also collision implemented, it affects the camera movement, disallowing the camera to go inside the terrain (collision is based on density function).
